carrying members I'I Yi I', on the guide devices I2', I3, comprise: a `power mechanisml. and a movable device I6, the devicel I6 having separate a reciprocatable piston I5b, which is connected tothe inner endotfarod I5c. The outer end of the rod is pivotallyconnected to the inner end -poi'tionfof a-bloc'kfl'd, the outer end portion of s the latterI being connected to the leg IIa of the adjacent load carrying member II remote from the 'side Wall 'Ib'. The opposite end portions of the cylinder I5a are provided with fluid connections I5", I5, to which fluid flowV pipes I5e, I5e', are connected, --the latter leading to a suitable valve. mechanism (not shown), which is Vmounted on the truck frame Irl,V and controlled by a Vlever I5.4 |Fnefluidsuch asvoil) is supplied under pressure in a Well knot/,1r manner to either .pipe

The'inner face' of 'the block I6@ and adjacent sid'efedges of the panels provide a guide for a "slide Id. The slide It'd is formed with an opening in which isv suitably xedY a pin Iethe outer end :of'whi'c'h extends lthrough an opening IBf formed in the ladjacent reev'ing element "I'Bb, a cott'er 'pin 16g on the outer 'end portionof. the Ypin engaging v.a washer It'g" lto sef cure' the element fsb tothfsude 16d-.j Thegsude elongated on an axis which intersects the axis of the path traversed by the flexible member on the reeving element ISD. The slide Id is adjusted outwardly endwise of its guideby a screw Ila. threaded through the inner side of the block IEC in line with and at right angles to the clamping screw il and adapted to engage the latter. In this arrangement, upon loosening the screw I'I, and operation of the screw I'Ia to move it endwise inwardly, the slide i601 may be adjusted to take up slack in the flexible member I6, following which operation the screw II is tightened to secure the slide ld in adjusted position.

The respective reeving elements Ita, Ib, may consist of sprockets, where the member IB consists of a chain, but where a flexible member I5 of a different type is used, rollers or pulleys may be employed as reeving elements. In the use of sprockets or rollers, the pins I5x, Isc, serve as shafts therefor. I prefer to use an endless chain and to employ stationary reeving elements, as shown, each having a semi-circular outer end wall Ia: (see Fig. on which the cross or end bars of the links ride during movement of the chain, the inner side plates of the chain links having an overlapping relation to the opposite faces of the elements Ia, I6b, as shown in Figs. 6, 7 and lO, whereby the chain is movably supported on these elements. Preferably the cross or end bars of the chain links are provided with rollers which roll on the semi-circular end walls of the reeving elements Ita, Ib. By preference, the reeving elements Ia, I6b, are so mounted, as above set forth, that theaxes of the walls |522, about which the chain It reeves, are in alinement with the axis of the cylinder loa. In this arrangement, the upper and lower runs of the chain i5 are equally spaced from and at opposite sides of the axis of the cylinder I5a and parallel to the direction of movement of the piston rod I5c.

In the form of construction shown in Figs. 1 to 14, inclusive, I provide a connection I8 between the leg Ha of the load carrying member Il and the chain I6 and a selective connection i9 between the leg Ila' of the load carrying member I i and the chain I6. In such arrangement, when the piston I5b is operated in either direction, the load carrying member II is moved or adjusted on the guide devices I2, I3, and through the chain ES the member II moves the load carrying member II' in a direction, as determined by the selective connection I9. The connection I8 consists of a plate I8a suitably fixed to the inner side of the leg IIa for the member li adjacent the outer side of one run of the chain I5 (preferably the upper run thereof) The plate ESa extends laterally beyond the inner side of the leg IIa and such extended portion is formed with an elongated slot Ib in which an anchor I8c is removably seated, the anchor having on its lower side a boss |80' which extends into and nts between the end bars of a chain link; the anchor I8c in this arrangement provides a driving connection between the leg IIa, and flexible member or chain I6. The anchor ISC is secured in position by a key 20, as later set forth, and by preference the key is removably secured to the plate I8a by a screw 29a. This arrangement provides for disassembly of these parts in the event of breakage or other unforeseen condition. The extension on the plate I8a is provided so as to position the slot IBb where it is readily accessible and is disposed on the inner side of the leg IIa to permit maximum-movement of the load carrying member II outwardly. To secure the anchor I8c in the slot ISI? by the key20, the extension on the plate I 8c is formed with two through, parallelly related openings Id disposed at right angles to the slot |827 and the anchor I8c is provided with two through openings adaptedl to register with the openings I8d, the registering openings serving to accommodate a pair of pins 2N) mounted on a plate-20c and operating as a key to lock the anchor Icto the plate I8a. From the foregoing description it will be observed that the chain I6 is connected to the anchor l 8c, which in turn through the plate I8a is connected to the leg IIa of the member II. The screw 20a extends through the plate 20c and is threaded into the extension between the pins 20h to hold the anchor in its seat and the boss I8c in driving relation with the adjacent chain link. The connection I9 consists of separate plates ISa, I9b, suitably xed to the inner side of the leg IIa of the load carrying member II above and below the planes of the respective chain runs. Each of the plates Isa, ISb, is similar in construction to the plate I8a, the extensions thereon extending laterally beyond the inner side of the leg Ila and formed with slots I9a, I9b', respectively. .Each slot I9a, ISb, is adapted to removably receive an anchor 2 I, the anchor having a boss 2 Ia adapted to removably project into the adjacent link of the chain I6, when the anchor is seated in one of said slots I9a', I9b', to connect the leg IIa. to the latter. The anchor 2I is preferably similar in construction to the anchor IBc, except that one end thereof is extended to provide a handle 2 Im. The Vanchor 2I is selectivelyseated in eitherof said slots I9a', I9b, whereby the chain and connections between the latter and the legs Ila, IIa', co-operate to move the load carrying members II, II', on the guides I2, I3, relatively toward or from each other or the members II, II', on the guide devices I2, I3, as a unit, as later set forth. The extension on each plate Ia, I9b, is formed with two through, paralelly related openings I9c disposed at right angles to the adjacent slot in the adjacent plate and the anchor 2l is formed with two through openings 2lb which, when the anchor is seated in either of said slots, register with the openings ISc in the extension of the adjacent plate, the openings ISC, 2Ib, when in registry serving to accommodate-a pair of pins 2Ic on a plate 2Id to lock the anchor in position.V The plate 2Id is removably secured in position by a locking mechanism indicated as an entirety at 22.

Operation: referring to Fig. 3, it will be noted that the anchor I8c connects the leg IIa of the load carrying member II to a link on the upper run of the chain I6, whereas the anchor 2l connects the leg IIa of the load carrying member II to the lower run of the chain I6. With the load carrying members II, II', disposed at their outer positions on the guide devices I2, I3, if fluid pressure is supplied to the inner end of the cylinder Ia to move the piston I5b toward the side bar Ib (as viewed in Fig. 3), the piston will move the load carrying member II in the same direction and the latter through the chain I5 will move the load carrying member II' in the opposite direction; that is, the power of the cylinder-piston unit transmitted to one of the load carrying members II-, II,' will effect a simultaneous movement .-of the latter toward each other, as shown in dotted lines in Fig. 3, 91nd by Tevel. *51.191.193 @95.531131 .Supply 901%'.
